I have production asterisk 16.4 with dialplan on LUA and two SIP providers. The first provider give me trunk with maximum 5 connections and the second provider give trunck with 20 connections. I prefer to use the first provider for outgoing calls because it is cheaper, but it have only 5 lines. So, when user makes an outgoing call, I want to check current number of active calls on the trunk of first provider, and if that number is 5 then route the call throught second provider.
The question is - How can I get in dialplan number of active calls? Is there some functions or core variables? I know that I can get list of active channels in CLI by command "core show channels verbose", but how can I get somthing like this in lua dialplan?
Thanks to #arheops for the clue. This is a working example on lua.
ext = extension:sub(1); -- Remove leading 9
local providerA = tonumber(channel['GROUP_COUNT(provA)']:get());
app.Verbose("Active channels on provider A = "..providerA);
if providerA < 5 then
channel['GROUP()']:set("provA");
app.Verbose("Outgoing call throught Provider A "..ext);
app.Dial("PJSIP/"..ext.."#trunc_providerA");
else
app.Verbose("Outgoing call throught Provider B "..ext);
app.Dial("PJSIP/"..ext.."#trunc_providerB");
end;
app.Hangup();
You can set GROUP for each channel and after that cont GROUP_COUNT in dialplan

We are setting up a federated scenario with Server and Client on different physical machines.
On the server, we have used the docker container to kickstart:
The above has been borrowed from Kubernetes tutorial. We believe this creates a 'local executor' [Ref 1] which helps create a gRPC server [Ref 2].
Ref 1:
Ref 2:
Next on the client 1, we are calling tff.framework.RemoteExecutor that connects to the gRPC server.
Our understanding based on the above is that the Remote Executor runs on the client which connects to the gRPC server.
Assuming the above is correct, how can we send a
tff.tf_computation
from the server to the client and print the output on the client side to ensure the whole setup works well.
Your understanding is definitely correct.
If you construct an ExecutorFactory directly, as seems to be the case in the code above, passing it to tff.framework.set_default_context will install your remote stack as the default mechanism for executing computations in the TFF runtime. You should additionally be able to pass the appropriate channels to tff.backends.native.set_remote_execution_context to handle the remote executor construction and context installation if desired, but the way you are doing it certainly works, and allows for greater customization.
Once you have set this up, running an example end-to-end should be fairly simple. We will set up a computation which takes a set of federated integers, prints on the clients, and sums the integers up. Let:
#tff.tf_computation(tf.int32)
def print_and_return(x):
# We must use tf.print here, as this logic will be
# serialized and run on the clients as TensorFlow.
tf.print('hello world')
return x
#tff.federated_computation(tff.FederatedType(tf.int32, tff.CLIENTS))
def print_and_sum(federated_arg):
same_ints = tff.federated_map(print_and_return, federated_arg)
return tff.federated_sum(same_ints)
Suppose we have N clients; we simply instantiate the set of federated integers, and invoke our computation.
federated_ints = [1] * N
total = print_and_sum(federated_ints)
assert total == N
This should cause the tf.prints defined above to run on the remote machine; as long as tf.print is directed to an output stream which you can monitor, you should be able to see it.
PS: you may note that the federated sum above is unnecessary; it certainly is. The same effect can be had by simply mapping the identity function with the serialized print.
I want to print/get the incoming caller number in Twilio Flask app. I was referring to the twilio-ivr-phone-tree for this. I tried print(request.args) in the welcome function i.e the first method which is invoked when I receive an incoming call. But it prints an empty ImmutableMultiDict([]).
Am I missing something? Any help is appreciated. Thanks in advance.
To -ve voters, post a comment for doing so. It helps to increase the quality of the question and make stack a better place.
The incoming call request information can be obtained in a Flask app using request.values
these are they keys of the diction returned:
atts = ('AccountSid',
'ApiVersion',
'CallSid',
'CallStatus',
'Called',
'CalledCity',
'CalledCountry',
'CalledState',
'CalledZip',
'Caller',
'CallerCity',
'CallerCountry',
'CallerState',
'CallerZip',
'Direction',
'From',
'FromCity',
'FromCountry',
'FromState',
'FromZip',
'To',
'ToCity',
'ToCountry',
'ToState',
'ToZip')
The main problem is the Twilio request has a form content type and the raw data will be consumed leading it to appear empty as described in this answer.
However request.get_data() can print the whole POST and you can easily find that the key From holds the caller's phone number.
So, to access it you need request.form['From'] and it fetches the caller's number to the local environment.
I have been using the following URL for the past 3 years without issue. However, it has stopped returning results.
URL:
https://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("ARSARS")&env=store://datatables.org/alltableswithkeys
Now returns the following:
<?xml version="1.0" encoding="UTF-8"?>
<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:count="0" yahoo:created="2017-11-02T09:33:25Z" yahoo:lang="en-AU">
<results/>
</query><!-- total: 9 -->
Notice how there are no results, it simply has the tag "results".
I have tried on this many different computers and browsers. I have also tried changing the currency combinations, but no luck.
Can anybody spot what I am doing wrong?
Yes, it looks like Yahoo has discontinued their Currency Converter API service.
I found a different site : https://currencylayer.com/
They let you request currency rates (1 USD = 168 other currencies). If you make less than 1000 requests per month, it is free (if you need more, they have different subscriptions : https://currencylayer.com/product).
You just need to sign up and receive your own Access Code. Once you have that, then you simply make the call http://apilayer.net/api/live?access_key= and it will return JSON of the other currency rates.
They also have code examples in PHP, JavaScript, and Java at https://currencylayer.com/documentation
Found it very easy to get started using their API right away.
I think the API is down.
I am similarly receiving "results"=nullfor the query:
http://query.yahooapis.com/v1/public/yql?q=select+%2A+from+yahoo.finance.xchange+where+pair+in+%28%22GBPEUR%22%29&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys
Setting diagnostics=true in the request yields:
`
[execution-start-time] => 7
[execution-stop-time] => 12
[execution-time] => 5
[http-status-code] => 999
[http-status-message] => Request denied
[content] => http://download.finance.yahoo.com/d/quotes.csv?s=GBPEUR=X&f=snl1d1t1ab
`
If anyone knows more than me about what this might imply I'd be glad to hear it!
Yahoo is aware of this issue and their engineers are working on it:
ref: https://forums.yahoo.net/t5/Yahoo-Finance-help/http-download-finance-yahoo-com-d-quotes-csv-s-GOOG-amp-f/td-p/387096
Very sadly and quite outrageously Yahoo decided to stop this service without any warning.
See admin message here
So many services depend on it, it's like Google saying they would suddenly stop their maps API... At this point I am blocking yahoo in our DNS so no one in our company will ever use Yahoo again since they are not a reliable entity.
I've been trying to find a way to connect my Windev application using the Quickbooks SDK.
I wish to connect to my local QB instance using the qbXML API.
I've been able to get a reference to the library using :
myconnection = new object Automation "QBXMLRP2.RequestProcessor"
However, when it comes to the OpenConnection2 method, I only get errors. Either "missing parameter" or "invalid parameter". I am aware that I should pass a "localQBD" type to the function, but I have not found out how to reference it. The following represents my invalid script.
myconnection>>OpenConnection2("","My Test App", localQBD)
How can I achieve a connection to QB through Windev?
After much searching, I have found that I was on the right path using the automation variable type.
However, I have yet to find how to reference the constants provided by the library. Instead, I declare them beforehand like so
CONSTANT
omSingleUser = 0
omMultiUser = 1
omDontCare = 2
qbStopOnError = 0
qbContinueOnError = 1
ctLocalQBD = 1
ctLocalQBDLaunchUI = 3
FIN
Which gives us this working example
myconnection = new object Automation "QBXMLRP2.RequestProcessor"
ticket = myconnection>>BeginSession("",::omDontCare)
XMLresponse = myconnection>>ProcessRequest(ticket,XMLrequest)
myconnection>>EndSession(ticket)
myconnection>>CloseConnection()
delete myconnection
A huge thanks goes to Frank Cazabon for showing me the proper constant values.
I have a complete external WinDev component that accesses QB and a helper program that can generate the WinDev calls in the correct order with the correct spelling and provides an OSR for all the QuickBooks fields and modules.
I have a similar product for the Clarion language and am in the final stages of the WinDev version. Contact me if you are interested. qbsnap at wybatap.com
I have a problem with changing the standard options used by an Axis 1.4 generated web service client code.
We consume a certain web service of a partner who is using the old RPC/Encoded style, which basically means we're not able to go for Axis 2 but are limited to Axis 1.4.
The service client is retrieving data from the remote server through our proxy which actually runs quite nicely.
Our application is deployed as a servlet. The retrieved response of the foreign web service is inserted into a (XML) document we provide to our internal systems/CMS.
But if the external service is not responding - which didn't happen yet but might happen at anytime - we want to degrade nicely and return our produced XML document without the calculated web service information within a resonable time.
The data retrieved is optional (if this specific calculation is missing it isn't a big issue at all).
So I tried to change the timeout settings. I did apply/use all methods and keys I could find in the documentation of axis to alter the connection and socket timeouts by searching the web.
None of these seems to influence the connection timeouts.
Can anyone give me advice how to alter the settings for an axis stub/service/port based on version 1.4?
Here's an example for the several configurations I tried:
MyService service = new MyServiceLocator();
MyServicePort port = null;
try {
port = service.getMyServicePort();
javax.xml.rpc.Stub stub = (javax.xml.rpc.Stub) port;
stub._setProperty("axis.connection.timeout", 10);
stub._setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, 10);
AxisProperties.setProperty("axis.connection.timeout", "10");
AxisProperties.setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, "10");
AxisProperties.setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, "10");
AxisProperties.setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, "10");
logger.error(AxisProperties.getProperties());
service = new MyClimateServiceLocator();
port = service.getMyServicePort();
}
I assigned the property changes before the generation of the service and after, I set the properties during initialisation, I tried several other timeout keys I found, ...
I think I'm getting mad about that and start to forget what I tried already!
What am I doing wrong? I mean there must be an option, mustn't it?
If I don't find a proper solution I thought about setting up a synchronized thread with a timeout within our code which actually feels quite awkward and somehow silly.
Can you imagine anything else?
Thanks in advance

I think it may be a bug, as indicated here:
https://issues.apache.org/jira/browse/AXIS-2493?jql=text%20~%20%22CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY%22
Typecast service port object to org.apache.axis.client.Stub.
(i.e)
org.apache.axis.client.Stub stub = (org.apache.axis.client.Stub) port;
Then set all the properties:
stub._setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, 10);
